Sudoku Napkins

When I go to a meeting I usually arrive early with 20 minutes. So, I play in my car a Sudoku game at my cell phone. Will be nice if after the lunch I can play a Sudoku on the napkins till the check come.

Ever get to that point in a meal where you are waiting for the next course and conversation is a bit lacking? So, for something to do, you turn to your napkin and start fiddling with it? Well how about playing Sudoku on it instead?
